COUPE QUATTRO INSTRUMENT PANEL BULBS - AGAIN!!

[Porsray@aol.com]

A couple of days ago, I asked about the OSRAM number for some instrument
panel bulbs on my Coupe Quattro.  The replies I got all said that it is an
OSRAM no. 2721.  Well, did a little digging for an errant part in my
workshop,
and came across a 2721 bulb still on the original backing card.
 Unfortunately,
 it is not the one I need.

Specifics are:

1) OSRAM 2721 is a very tiny glass bulb with two electrical connectors
sticking out the end.  There is no base (plastic or otherwise) on the bulb;
it is 
entirely bare except for two lead connectors.
  
2) Bulb I need has about the same size glass bulb, but there is an integral
black plastic base on the end.  This allows you to place it in the socket
hole
on the instrument panel circuit board and secure the bulb by turning it with
a
small screwdriver by approx. 1/4 turn (like a bayonet socket).

Audi part no. for  needed bulb is 893 919 040 (I believe).  I have a
suspicion 
that a change was made to this style bulb with the approx. date of Coupe
introduction; my parts microfiche shows what looks like the OSRAM 2721
with an associated separate base but no part no. linked to it.

I think the Audi part no. for the OSRAM bulb is N 017 751 2

OK, folks, what do you say?
